Experemented with different props on my UCD60/SAITO100 these weekends.
It seems 16X4 is too large for this motor, but 15X4 is too small
What about the idea to cut 16X4 to 15" in length. Just cut about 1/2" from each tip. It seems it should be the best prop for ucd60/saito100.
Anyone tried that? What do you you think?
